To all whom 'it may concern.'

lie it known that l', CHARLES vW. PALMER? :t citizen oi the United Sintes, residing at Sandpoint, in the county of Kootenai and State oit' idaho. lmve invented new and useiul lm irovcinents in VniveSrini?" Liftersof which tl e 'followingis n specification.

rlhe present invention relates to improve-i ments in tools or implements of the Class having juive which :ire relatively movable to operate upon the part or parte engaged therewith7 sind the prin'nii'y object of the invention is to provide e. novel :md improved tool ot this churneter which is particularly adapted for use in lifting-thc springs snch :is used, upon the valves of internal combustion engines, to enable the springs to be de` tnched From the valve stoms preparatory to the ren'iovxil of the vulves. the tool provided 'for this purpose by the present invention eetini;r to lift the spring eusiiy and to hold the'.

springsecurmlly in lifted position, whereby the vnlve niny he removed with facility, and the jans oi the tool :1re 'forked and provided with Ineens for verving the distnnce between the forks olt euch uw. thusl enabling the tool lo he mljnsted to accommodate it to dimeib sions of the vulve stein, spring" seat collar, or: the spring n `1dining);` ineens, und also to the vulve litter or other part against which the tool rests. i

'Other objects of thel invention. are to provide uy tool which is :adapted to servo not only :is :i vulve springs lifter hut which muy also he used ns :i vise or chimp to gripend hohl *parts upon which work is to he per-l iormcil amd, io hohl the head of ai holt against turning while the `not is tightened thereon Y To thcschnd other ends, the invention consists in certain improvements, and coinloi nations :1nd arrangements ot' parts, ellas `will hc hereinafter more fuily desoribedthe novel tentures being; pointed ont particu@ lerly in the claims ut the end of the specification. ln the uccornl'ninyingr drawings:

The tool is especially adapted' to t'ultil the requirements-of lifting the springs of valves yof internal combustion engines preparatory to the removal of the Valves, although it is also capable of ciiicient use for the pur oses to he hereinafter described. it 'is to p e Aund stood. that the invention is not restricted to the precise construction shown, es equivalent constructions are contemplate-d end will be ineluded within'the scope'of the cieiins.

The tool comprises e pair of jews i end 2", the operative portions of these jaws being forked. and ineens is provided for .morfine ythe jews toward and fromone another for maintaining the vjaws in 4guiriillelism 'et all adjustments thereof. Prefernhijrf, und as shown, each jaw comprises :i strip of steel or other suitable metal whichr` as shown in 'Fig'. 5 is doubled intermedietely to bring 'the two ends of the. strip into substantial parallelism, thus forming :irins the extremities of which are spaced lntfernliy and conn stitute prongsn of :i fork. Means is prow' vided for varying the distance between the prongs on each jaw, such ineens eoniprising :1 nut i-Which is rotatably .fitted to the ,inner side ot' one arnl of the jaw and n screw 5 which is `fixed' to the initier side ot' the other arm of the-jew, the nntlengagingtlie screw and being rotatable by e-Wrencht'o 'fil cause the forks of the jaw to, spreed. or onit is shouldered und rotatably fitted in n bearing bloeit 8 secured to the other jew? the momes parallelism between the jaws turing relative n'iovement between them. l 2..
